<p><span class="user-mention" data-user-id="133224">@Nikita Popov</span> Do you think it would be worth it to try to backport the LLVM commit from <a href="https://github.com/rust-lang/rust/issues/86758#issuecomment-888595051">https://github.com/rust-lang/rust/issues/86758#issuecomment-888595051</a> (it's included in LLVM 13). Doing so would unblock <a href="https://github.com/rust-lang/rust/pull/81825">https://github.com/rust-lang/rust/pull/81825</a></p>

<p>Or do you expect the LLVM 13 upgrade PR to be merged soon?</p>

<p>Assuming there are no complicated dependencies involved here (doesn't looks like it), I'd definitely go for the backport. LLVM major version updates can take a long time, depending on how bad the release is.</p>
